HandlerMethodArgumentResolver
public abstract class AbstractCookieValueMethodArgumentResolver extends AbstractNamedValueMethodArgumentResolver
A base abstract class to resolve method arguments annotated with@CookieValue
. Subclasses extract the cookie value from the request.An
@CookieValue
is a named value that is resolved from a cookie. It has a required flag and a default value to fall back on when the cookie does not exist.A
WebDataBinder
may be invoked to apply type conversion to the resolved cookie value.- 从以下版本开始:

构造器详细资料
AbstractCookieValueMethodArgumentResolver
public AbstractCookieValueMethodArgumentResolver(ConfigurableBeanFactory beanFactory)
- 参数:
beanFactory
- a bean factory to use for resolving ${...} placeholder and #{...} SpEL expressions in default values; ornull
if default values are not expected to contain expressions

supportsParameter
public boolean supportsParameter(MethodParameter parameter)
从接口复制的说明:HandlerMethodArgumentResolver
Whether the given method parameter is supported by this resolver.- 参数:
parameter
- the method parameter to check- 返回:
true
if this resolver supports the supplied parameter;false
otherwise
createNamedValueInfo
protected AbstractNamedValueMethodArgumentResolver.NamedValueInfo createNamedValueInfo(MethodParameter parameter)
Create theAbstractNamedValueMethodArgumentResolver.NamedValueInfo
object for the given method parameter. Implementations typically retrieve the method annotation by means ofMethodParameter.getParameterAnnotation(Class)
.- 指定者:
createNamedValueInfo
在类中AbstractNamedValueMethodArgumentResolver
- 参数:
parameter
- the method parameter- 返回:
- the named value information
handleMissingValue
protected void handleMissingValue(String name, MethodParameter parameter) throws ServletRequestBindingException
Invoked when a named value is required, butAbstractNamedValueMethodArgumentResolver.resolveName(String, MethodParameter, NativeWebRequest)
returnednull
and there is no default value. Subclasses typically throw an exception in this case.- 覆盖:
handleMissingValue
在类中AbstractNamedValueMethodArgumentResolver
- 参数:
name
- the name for the valueparameter
- the method parameter- 抛出:
ServletRequestBindingException
